环境温度过高或散热条件不好时，应注意不要长时间开屏，屏幕应安装在-10℃~40℃温度范围环境，超出温度范围时需加装温控设备。严禁在任何发热源附近进行LED显示屏安装工作.
When ambient temperature is too high or cooling condition is bad, users had better not to turn on the screen for a long time. Screen shall be installed in temperature from -10℃~40℃, over environment temperature range,temperature control equipment must be installed. it is forbidden to install LED display near any heat source.
3. 环境湿度 Ambient humidity
安装显示屏时，环境相对湿度应在30%~70%范围，当室内环境湿度低于30%时容易产生静电；当室内环境湿度高于70%时容易导致电子器件受潮.
When installing screen,ambient relative humidity should be in the range from 30% to 70%, it is prone to get static electricity when the indoor humidity is below 30%;when the indoor humidity is higher than 70%,electronic components are easy to get damp.
4. 腐蚀性气体环境 Corrosive gas environment
请不要将显示屏安装在含有酸或碱成分等腐蚀气体环境中，如化学药品仓库附近.
Please do not install the display in corrosive gas environment containing acid or base components, such as chemical warehouse.
5. 电磁辐射环境 Electromagnetic radiation environment
请不要将显示屏安装在电磁辐射、射频辐射超过场强5V/m干扰源的环境中，如有需要必须做隔离处理.
Please do not install the display when electromagnetic radiation environent is over field strength 5v/m. if necessary, isolationtreatment should be taken.
6. 保持电源稳定 Steady power supply
保持供电电源稳定必要时在配电箱内加装浪涌开关，并做好接地保护避免雷击，在强雷电天气及其他恶劣的自然条件下不要使用显示屏.
If necessary, users have to install surge switches in the distribution box and ground fault protection to avoid lightning strikes, Do not use the display in strong lightning and other severe weather.
| | 7. 严禁屏体接触水，金属粉尘等易导电的物质
Conductive material is strictly prohibited to contact display, such as metal dust and water.
显示屏尽量放置在低灰尘的 环境中，否则会对显示效果造成影响，同时会对电路造成损害。如果因为各种原因接触到水，请立即断电直至屏体单元板干燥后方可使用.
Screens are placed in the environment of lowdust as far as possible, otherwise it will affect the display effects, as well as damage the circuit, if exposed to water for various reasons, please immediately power down until the screen unit dry.
8. 控制色彩显示 Controlling colors.
不要使显示屏长时间处于全白色、全红色、全绿色、全蓝色等全亮画面，因为这样会影响显示屏使用寿命.
Do not display a long time in a white,red,green,blue or other bright screen, because this will affect the display lifetime.
9. 控制使用时间 Controlling time.
LED显示屏大屏幕每天至少休息2小时；一般每星期至少开启屏幕两次以上（特别是梅雨季节时需要每天开启一次）且点亮时间需要2小时以上.
LED display at least rest 2hours a day,Normally turn on the screen at least twice a week or more (Especially in the rainy season it is necessary to turn on the display every day), and it maintains more than 2 hours every time.
10. 定期全面检修 Regular overhaul.
LED显示屏需要定期检查，线路有无损坏，如不工作要及时更换线路，有损坏时要及时修补或者更换.
LED display requires regular inspection to check circuit damage, if it does not work, change it in time, if circuit damages, it should be repaired or replaced.
11. 安全警示 Security alerts
LED显示屏在安装时，要确保安全，工厂仅提供产品好框架固定参考方案，相关安全方面用户需结合当地情况和现场条件，提请有关方面论证好确认.
Users must ensure safety while installing led display, the factory only offers products and reference programs of frame fixation, users can ask relevant authorities to confirm according to local conditions and field conditions.
